EVALUATION OF SOIL BEARING CAPACITY IN SELECTED AREAS WITHIN SOKOTO METROPOLIS
M. Yanda, B. A. Olawumi

ABSTRACT
This project emphasizes on the importance of bearing capacity of the soil for any construction project. A large number of buildings are damaged because of an inappropriate design of foundation. The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Some of the questions addressed in this project are, how water affects the bearing capacity of soil, changes in the bearing capacity with addition of cement and variation in the bearing capacity values of soil in different location/ area within Sokoto metropolis . Tests were conducted on soil samples. The strength of soil was related to depth of penetration of surcharge for which penetrometer records the values obtained. Graphs were plotted for different soil samples taken in different area. Conclusion was drawn that soil Rujin Sambo and Old Airport areas of Sokoto has bearing capacity values of 910KN/M2 and 950KN/M2 respectively and were recommended with strip foundation for Bungalow e.t.c While the soil in Mabera has a bearing capacity of 140KN/M2 which implies low below the minimum bearing capacity to withstand bad foundation. It was recommended that it should be stabilized with cement to at least a bearing capacity of 150KN/M2 in other to withstand structure.
